The Liberty occurrence is located at 1219 metres elevation near the junction of Carlyle and Keen creeks. The Liberty occurrence is located on ground covered by the Liberty minerals claim group consisting of the Stars and Stripes (Lot 4899), Liberty (Lot 4900), Sixteen to One (Lot 4901), Mastodon (Lot 4902) and Last Chance (Lot 12853) Reverted Crown grants. Kaslo, British Columbia is located 15 kilometres to the east.

Exploratory work was first conducted on the Liberty Group in the late 1890s. Workings consist of eight or more short adits and shafts that explore two or more fissure-vein lodes striking northeast and in part conforming with structure of the host metasediments.

Regionally, the area lies on the western margin of the Kootenay Arc, in allochthonous rocks of the Quesnel Terrane. In the vicinity of the occurrence, the Quesnel Terrane is dominated by the Upper Triassic Slocan Group, a thick sequence of deformed and metamorphosed shale, argillite, siltstone, quartzite and minor limestone. Rocks of the Slocan Group are tightly and disharmonically folded. Early minor folds are tight to isoclinal with moderate east plunging, southeast inclined axial planes and younger folds are open, southwest plunging with subhorizontal axial planes. The sedimentary sequence has been regionally metamorphosed to lower greenschist facies.

Immediately west of the occurrence, the Slocan Group has been intruded by the Middle Jurassic Nelson intrusions which comprise at least six texturally and compositionally distinct phases ranging from diorite to lamprophyre. The most dominant phase is a medium to coarse grained potassium feldspar porphyritic granite. Several feldspar porphyritic granodiorite dikes, apparently related to the Nelson intrusions, also cut the sedimentary sequence near the occurrence (Paper 1989-5). The sedimentary sequence has been affected by contact metamorphism from the emplacement of the nearby Nelson intrusions.

The Liberty occurrence is located immediately east of the contact between the Mount Carlyle stock of the Nelson intrusions and metasediments of the Slocan Group, which the Liberty occurrence is hosted in. Metasediments include interbedded slate, argillite, andalusite schist and limestone striking north to northeast. Quartz porphyry dikes and sills intrude. The border phase of the potassium feldspar porphyritic granite Mount Carlyle stock is coarse grained hornblende diorite and quartz diorite.

The lowest lode, at about 122 metres above Keen Creek, has been explored by at least two adits. The lode strikes 055 degrees and dips 60 degrees to the southeast. Mineralization intersected consists of streaks and pockets of galena, pyrite, chalcopyrite and sphalerite in a gangue of quartz and siderite. Less than 30 metres vertically above, an adit intersects porphyry and quartzite hosting a mineralized fissure. The fissure strikes northeast and dips 60 degrees southeast. At the face of the adit the lode is 60 centimetres wide and carries pyrite and galena in a gangue of quartz, siderite and brecciated wallrock. Copper staining was observed. Less than 113 metres vertically higher an adit intersects a fissure striking 055 degrees and dipping 75 degrees southeast. Other adits at higher elevations were unsuccessful at finding further mineralization.

Production records for the Liberty occurrence indicate ore was produced in 1899, 1923, 1925 and 1979 totalling 1457 tonnes. This ore yielded 61,193 grams silver, 12,426 kilograms lead, 103,331 kilograms zinc, 976 kilograms cadmium and 717 grams gold.

In 2013, Agave Silver Corp. examined the area as the Kaslo property
